Resistivity is an intrinsic electrical property of a given material, defining how it resists the flow of electrical current. The…
When we use a set of electrodes to measure resistivity, what we actually record in the field is an apparent…
Arguably, the most common geophysical methods for geotechnical applications are GPR, resistivity and seismics. In most situations, especially for complex…
EM Locators (EML, electromagnetic pipe & cable locators) is a universal technology for locating and tracing buried utility lines. As…
The footprint of a GPR describes the radiation pattern form, emitted by a GPR antenna. The size and shape of…
An electrode test, or electrode contact test, is a feature on the ABEM Terrameter LS2 which checks the quality of…
Geophysics is the physics of the Earth, but it has developed into a field with much broader implications. Geophysicists use…
Yes, resistivity and GPR make an excellent pairing and together will often provide a more complete visualization of the bedrock depth…
TEM measurements are not possible in urban areas due to the numerous sources of electromagnetic noise that are present. TEM…
